Master Koin Kode:In order to build up an unlimited amount of Koins,
complete the following:

Select Versus mode and load a profile for each
player. Before this can be done, each player needs to have a decent
amount of Koins already in his/her profile so that large amounts can be
accessed for this wager. Open up the wager screen and wager one round
as you normally would, then after the first battle have only player 1 open
the wager screen, not player 2. Player one should press either Left
or Right on the D-Pad, and a koin sound should be audible. Unfortunately,
this cheat does not allow the player to actually see the Koins being bet,
but they go in this order:Press Right once, then Up = OnyxPress Right twice, then Up = JadePress Right three, then Up = RubyPress Right four, then Up = GoldPress Right five, then Up = PlatinumPress Right six, then Up = SapphireNext, press Up, and a sound should also confirm
that Koins are being bet. Keep pressing Up until the sound stops
and the wager is at its max, then hit the wager button again to close the
screen. Both players should now choose their characters, enter a
versus match, and let player 1 beat player 2. Player 1 will win Koins,
but player 2 will not lose any Koins. Keep doing this to earn as
many Koins as you want.
